List The Three Minerals In Granite

Granite s mineral composition is mainly quartz and feldspar.

List the three minerals in granite. Granite is an igneous rock of plutonic origin meaning it formed beneath the surface rather than above ground. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. The crystals in granite provide a variety of mixed colors feldspar pink or red mica dark brown or black quartz clear pink white or black and amphibole black.

Granite is a conglomerate of minerals and rocks primarily quartz potassium feldspar mica amphiboles and trace other minerals. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. Learn more about the properties and uses of granite in this article. It is mainly composed of quartz and feldspar although it may contain smaller amounts of other minerals such as mica and amphibole.

It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. Granite is high in quartz about 25 feldspar and mica. Approximately 80 percent of this igneous rock is made up of these two minerals the other minerals found in granite are mica and amphibole.
